Description

The Orion-class, HMS Orion (52), 1914, as the lead ship of her class of 4 was laid down in November 1909. Launched in August 1910 and commissioned in January 1912, she and her class would feature the new 13.5-inch gun. This along with their thicker armour would lead to them being colloquially referred to as "super-dreadnoughts". Despite this and despite being active for the entirety of the First World War, she would see relatively little combat. Seeing action in the infamous Battle of Jutland and the Action of the 19th of August, the vast majority of her career during the war was simply routine patrols and training. Following the end of the war, Orion would serve as a gunnery training ship for about a year before being sold for scrap in 1922.

Introduced in Update "Air Superiority", HMS Orion follows HMS Dreadnought in the Bluewater fleet. Compared to Dreadnought, she features heavier armour and more powerful guns at 13.5-inch compared to the 12-inch battery of Dreadnought. Notably, she maintains the same top speed despite the increase in capability. Unlike Dreadnought though, HMS Orion comes in a 1914 refit, meaning she lacks even the paltry pair of 3-inch anti-aircraft guns. This means aircraft have essentially free reign over the Orion, and is a very noticeable weakness.

Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armaments separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips on preserving survivability for the "Usage in battles" section. If necessary, use a graphical template to show the most well-protected or most vulnerable points in the armour.

Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).

Pros and cons

Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".

History

Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the ship and adding a block "/History" (example: https://wiki.warthunder.com/(Ship-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the ship's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
